Zwave + Habmin = nullPointerException

Hi all

I’m struggeling with the zwave binding. I was trying to integrate a Z-Wave AEOEZW090-C Aeon Labs USB Stick (also known as Z-Stick Gen-5 Z-Wave Plus USB Controller) and the Sensative Strip. According to this How-To-Manual from @MikeEast there is in Step 8 a Parameter section where something has to be changed. Since this section is for any reason not available in my setup

I was trying the latest snapshot of the zwave binding but this causes the following NPE when I’m using HABmin.

Has anyone an idea what causes this NPE and how I can get to the parameter section?

Thanks and regards
John

Could be a problem in 1.8.2, take a look here:

Continuing the discussion from 1.8.2 and Habmin:

The design of habmin is such that unless the device has checked in, it will refuse to change parameters. (i.e. the colored status dot is something other than gray.) Now I don’t remember that throwing any NPEs if you tried to change a parameter when a device hadn’t checked in yet, but maybe something changed with 1.8.2.
